C. Service Connections
1. Electrical
The electrical power supply connection to the dryer is
made into the electrical box which is located in the front of
the dryer's base. To get into the box, remove its screw-on
cover. Connect the supply power wires into the power
distribution block which is located at the lower center of
the box's 1 eft side.
The power distribution block has three (3) poles for
connecting the three (3) lines of 3-phase power. If the
dryer was built to run on 3-phase/4-wire power, connect the
neutral wire into the 3-position terminal block located above
the power distribution block.
Before turning on power to the dryer, measure the supply
voltage to ensure that it matches the dryer's specified input
voltage. This input voltage is marked on the aluminum data
tag, located on the inner right wall of the dryer's right-
hand control box. Supplying the wrong voltage or low voltage
will result in serious damage to the dryer or lead to poor
dryer performance. A fused disconnect switch for the supply
power must be provided near the dryer.
